This viewgraph presentation discusses the role of AIC which is to develop networks & networking standards for use in
aviation that define methods, means and services for the transport of data, including quality and security.

The air/ground voice communication between air tra c controller and aircraft does not provide any means of automatic
speaker identification and is therefore susceptible to call sign confusion and originator ambiguity. In the near future the
analogue VHF radio will not disappear from avionic communications. With an add-on to the analogue radio it is possible to
automatically detect the originator of a voice message. Watermarking allows the embedding of an identification into the voice
signal. The tag is ideally not audible to the human listener, but is for an electronic system clearly detectable. Requirements
on the system are driven by functionality and deployment constraints. The reviewed in-band modem system is in our opinion
not fully compatible to the legacy radio infrastructure. The spread spectrum watermarking approach shows room for
improvements in functionality and capacity. With informed embedding and known host state algorithms a new trend in
watermarking promises large capacity increases.

This is a presentation that points out US future airspace plans agenda. Topics include CNS-ATM plans on
communications, navigation surveillance, air traffic management, safety and security. The report also discusses RNAV routes
which are critical to reduce voice and airspace congestion, the recommendation of immediate development and
implementation of RNP/RNAV routes in terminal environment, and that routes should be non-sensor specific, allowing the
most aircraft to participate.
